I am using Dell Inspiron 11 3000 2-in-1 (3147) too.
I don't have any luck with acpi=off (Boot up process stuck at ath9k and irq problems) acpi = force/ht did not help either (Able to boot up)
I tried nolapic with some success (Sometimes it will not boot up, stuck at i2c_designware and irq 32 problems)
I have also tried reboot=(every combination of flags) (Able to boot up)
Currently, it will not shutdown/reboot/resume.
Shutdown and reboot will hang at "will now halt/reboot"
